"He just has the ability to take a professional at-bat," D-backs farm director Mike Bell said. "He swings at good pitches, he's able to lay off the bad ones and that's ultimately what you want to do as a hitter. He's just got a really good feel to hit and knows how to put together a good at-bat. He's just a mature hitter."

The 21-year-old Smith demonstrated his feel for the strike zone with 27 walks and just 24 strikeouts.

"That's hard to do and it's even harder to do in your first year," Bell said. "That's extremely impressive."

Defensively, Smith has shown good footwork around the bag to go with soft hands and a strong arm.

"You don't think about that too much from a first baseman," Bell said of Smith's arm. "But it's important to have that and he's got a strong, accurate arm."

The one thing Smith did not show his first year of pro ball was power. He hit 13 homers in his final year for the Cavaliers, but he did not hit one with Hillsboro, though Smith did have 15 doubles.

"I know he didn't hit for power, but it's in there," Bell said. "The ball comes off his bat really well. He finds the barrel plenty. The power will come. He's going to hit some home runs. He finds the barrel too much and hits the ball too hard not to."

As a polished college hitter, Smith is likely going to be a quick riser through the system. With Paul Goldschmidt under contract for the next two seasons there is no reason to rush Smith, but there seems little doubt he's on his way.
